public class ExampleHyperHeuristic2
extends HyperHeuristic

This class shows an example hyper-heuristic which demonstrates that each ProblemDomain object has a modifiable solution memory. it is intended to be read after the ExampleHyperHeuristic1 class has been understood.

this hyper-heuristic maintains a memory of ten solutions. A randomly chosen low level heuristic is applied to the best solution in the memory, and the solution is immediately accepted. the new solution overwrites the old solution at the same memory index. If the solution is worse, then the best solution in the memory will most likely be different now. therefore, the memory is searched for the current best solution, so that it can be used in the next iteration.
